Project Title
Design and Development of UAV Video Link MODEM with Relay Transmission Capabilities
Project Area of Specialization
Project Summary
This project aims to develop a MODEM which will accept digital signals (basic sensor data or video signals) using one camera. The received data is converted into binary form, multiplexed, converted into frames, and then transmitted using a non- coherent scheme called DPSK modulation. Both the wired and wireless communication will be possible. The UHF band will be used for transmission which means both Digital and RF circuitry will be involved, and its circuit design and packaging will require conformance to thermal and electromagnetic compliance.
On the receiver side, MODEM will receive the data, de-multiplex it, convert it back to original formats and make it available to intended users, allowing them to configure the number of inputs and type of binary coding used for input.
Atleast two different frequencies will be used for transmission and reception so that it allows a relay type device to be used in between the transmitter and receiver MODEM as a communication relay.
These MODEMs find applications in telemetry systems including those used in Beyond Line of Sight (BLOS) UAVs.
Project Objectives
- To develop a video MODEM for digital camera input of Beyond Visual Line of Sight (BVLOS) UAV
- MODEM will use DPSK Modulation as it is non-coherent scheme and will not cause synchronization problem.
- MODEM shall comply with Airborne Form Factor
Project Implementation Method
- Implement design in simulation
- Select Hardware components
- Hardware Development
- Testing and Validation
Benefits of the Project
Assured efficient communication is a key performance parameter of BVLOS UAVs. Data and Video MODEM are main components of the communication link. The project aims to design an indigenous MODEM which presently is imported. As a product it will have utility in Strategic Organizations, Armed Forces & other BVLOS Drone users
Technical Details of Final Deliverable
